With expectations that Apple will be releasing a new iPhone in the fall, alongside the next major revision of iOS, we’ve been looking for signs that Apple’s preparing an iOS 6 beta version for its development community. We learn of just such an indication today, upon the discovery of some text strings attached to the latest iCloud beta.

Apple has new beta test going for its iCloud website, featuring a couple new web apps, but maybe the most interesting aspect of the site is the presence of a few lines that stand out in its source. There we see multiple mentions of requirements to sign in to iCloud through the iOS 6 beta before accessing the site.

A separate iOS 6 rumor expands on something we noticed back when Apple release iPhoto for the iPad. That software saw Apple start moving away from Google as its provider for map data. Supposedly, Apple’s going to break all ties with the release of iOS 6, introducing its own Maps app powered by map data and imagery acquired through companies Apple’s been snatching-up. The new Maps will supposedly feature some very impressive 3D content, courtesy of one of those acquisitions.

With any luck, Apple will start making iOS 6 available to devs around the time of June’s WWDC.
